ABSTRACT
Immigration and migration, albeit a steady force throughout human history, are reaching unprecedented proportions. There were 191 million immigrants in 2005, projected to reach 350 million by the year 2025 (United Nations, 2002, 2006). Adding to this statistic are the short-term migrants: assorted sojourners or expatriates, approximately one million international students each year (Open Doors, 1996/1997), and 874 million tourists in 2005, projected to reach 1.6 billion by 2020 (United Nations World Tourism Organization, 2006, 2008).
